ATENT HENRY MEYNELL, OF ACCRINGTON, ENGLAND.

SPECIFICATION forming part of Letters Patent No. 776,410, dated November 29, 1904.

Application filed April 16, 1904.

T0 at whom it may concern.-

Be it known that I, HENRYMEYNELL, residing at Accrington, in the county of Lancaster, England, have invented certain new and useful Improvements in Self-Contained Spindles for Spinning and Doubling Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to the lubrication of self-contained spindles for ring and traveler and like spinning and doubling frames. The usual type of oil-cup at present employed in connection with such spindles is inserted into the bottom of the bolster and secured therein by multiple screw-threads. It is found, however, that when the oil-cup has been filled and is being fitted into position a portion of the oil is displaced by the spindle-bearing and necessarily overflows and runs to waste.

In the accompanying drawings, Figure 1 is an elevation, partly in section, of a self-contained spindle having myimprovements applied thereto; and Figs. 2, 3, 4E, and 5 are respectively section and part sections of the oil-cup detached and illustrate certain modifications which will be hereinafter referred to.

Referring to Fig. l, I make the bolster a somewhat shorter than usual and provide the same with a detachable extension 7), adapted to act as a cup for holding the oil for lubricating the spindle. The oil-cup b has formed integral therewith a nut c, which is recessed from the top and tapped at (Z and is further hollowed out'to form a reservoir or chamber a. The tube f, which forms the upper part of the oil-cup, is made in one piece therewith and is of such a diameter that when inserted in the bolster an annular space or ring g is left between the periphery of such tube and the internal surface of the bolster. The cup having been filled with a suitable quantity of oil, the tubef is inserted in the bolster, where it fits nicely around the spindle-bearing it, and the nut c is then screwed onto the thread 2' on the bolster until the upper part of the tube f comes into contact with the shoulder j. The oil which is displaced by the spindle- Serial No. 203,472. (No model.)

bearing it runs down the channel or annular space 9 and so into the reservoir 0, whence it can be removed and used again when the spindle requires a fresh supply of oil. As the reservoir 6 may be made suflieiently large to accommodate any desired quantity of oil, absolutely no loss thereof can take place and a great economy is effected. The oil-cups can of course be removed and replaced while the spindles are in motion.

In Fig. 2 I have shown a canal or channel 74, of which one or more may be employed and by means of which the reservoir 0 may empty itself into the oil-cup b as the level of the oil becomes gradually lower therein, and the reservoir might be provided with a thor oughfare or channel I, as shown in Fig. 3, or with a projecting spout m, as shown in Fig. t, by means of which the cup could be filled from an oil-can..without detaching the same. When constructed in this manner, the oil-cup 5 may receive its supply of oil entirely from the reservoir. The various parts may be made of any desired size or proportion, so that the oil can be used to the best advantage. A jam-nut 0 is provided on the bolster (a for securing the oil-cup.

Fig. 5 illustrates the reservoir fitted with a small cook a, through which the surplus oil could be drained off, if required.
